WILLIAM It. BAKER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MCCORMICK HARVESTING MACHINE COMPANY, OF SAME PLACE.

GRAIN-BINDER.

eSPECIFICATION forming part of Letters Patent No. 339,123, dated April 6, 1886.

Application filed September 21, 1882. Serial No. 72,398.

To (til whom it may concern:

Be it known that I, WILLIAM R. BAKER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification.

As a rnle,all automatic binders now used to any material advantage in the field are provided with means for sizing the gavel in order m that the sheaves, when bound, may be of substantially uniform size, notwithstanding the natural variance in the thickness of the crop in different parts of the same field. In some this result is obtained by the use of positive speed-gearing under the control of the driver, requiring his constant watchfulness to determine the condition of the crop. In others,and, perhaps,at present the most popular class, an

automatic trip is acted upon by the accumn-.

2o lation of the gavel either within a special receptacle between the conveying and the binding mechanism or within the binding-receptacle itself.

My invention relates to the latter types, and

2 more especially to those where the tripping is determined within a packing-chamber forming the bindingreceptacle. In this form the exit from the receptacle is usually closed by a pivoted tripping-arm, frequently itself forming the outside compressor, and the grain confined between the decking and an overhead breast-plate is packed against it by alternatelyrnoving packingarms rising through slots in the decking, or by a revolving armed wheel or drum above or below such decking, and a trip-rod leads from the tripping'arm or compressor to a rock-shaft connected by suitable means with the clutch between the binding mechanism and a constantly-driven shaft upon 0 the harvester or hinder frame, so that when the compressor is pushed back upon its pivot the rock-shaft will be moved and the clutch will be thrown into engagement, alter which the binding operation immediately takes place.

4 5 Then the compressor is temporarily withdrawn to allow the discharge of the bound sheaf and immediately reset in position for action. I find that in practical use the grain in this and similar constructions will frequently bind and accumulate between the vibrating or rotating packing-arms and the upper and lower walls (No model.)

of the receptacle or packing'chamber before it reaches the outside trip-arm or compressor, and hence before the latter is operated a gavel of under size will have accumulated. Thus 5 the action of the machine will be rendered uncertain and the sheaves will not be uniform.

To obviate this difficulty I propose to make a section or the whole of the decking yielding and connected by an arm or hearing with the 6 tripping rock-shaft, so that the latter may be operated with equal certainty by the desired accumulation of grain whether it binds within the receptacle or not. This construction, also,

I propose to use either as the sole tripping agency or in connection with a tripping-compressor or outside arm, both acting independently or concurrently to start the clutch when the proper pressure is reached, and also whether it is a section of the lower or of the upper decking of the receptacle.

My invention therefore consists in combining with a tripping-clutch to start the binder and packing or feeding devices to compress the grain into the binding receptaclc or packingchamber a decking for said receptacle having a yielding section and a connection between said section and a clutch to trip the latter by the yielding of the section; in combining with the grain receptacle two yielding surfaces against which the gavel is fed by the packers, and connections between said surfaces andthe tripping-clutch to start the binder by the yielding of either or both; in combining with the trippingclutch to start the binder and with packing or feeding devices to deliver the grain into the biudingreceptacle or compress ing chamber a decking for said receptacle having a yielding section, a yielding arm or compressor closing the exit from said recep o tacle, and connections between said section and arm and the clutch, whereby the binder will be equally started at the yielding of one or the other, or of both; in combining with the tripping clutch to start the binder and 5 with a rock-shaft by which said clutch is dogged or shipped a decking for the grain-receplacle having a yielding section resting upon an arm from said rock-shaft, whereby the yielding of the decking as the grain is packed thereon too will move the shaft and cause the engagement of the clutch; in combining with a trippingclutch to start the binder and with the rockshaftby which said clutch is dogged or shipped a decking for the graiureceptacle having a yielding section, an arm from the rock-shaft upon which said section rests, and a movable arm or compressor engaging with another arm from said rock-shaft, whereby the shaft will be moved by the accumulation of grain against both the yielding section and the movable compressor, and in various other devices and details of construction accessory to the foregoing combination.

The machine which I have chosen for the purpose of illustrating my invention is of a Wellknown type manufactured by the Me- Gormick Harvesting Machine Company for sometime past, the essential features being that the outside compressor is pivoted upon a spring-sustained supporting-bar, which in turn is hinged to a heel-extension of the bindingarm to give an additional compression as the latter closes past the knotter, and is so controlled as to sink upon its pivot at the conclusion of the binding operation, to withdraw the compressor beneath the decking and allow the discharge of a sheaf. A rod from a rock shaft takes into an eye in a forwardly-extending portion of the compressor, so that as the lat ter is rocked back upon its pivot'by the press ure of the gavel it shall move the shaft, and by intermediate connections cause or permit the engagement of a clutch with a loose gearwheel upon another constantly-drivenrotating shaft mounted in bearings in the binding attachment, this gear wheel, through intermeshing Wheels, communicating motion to the gear and cam wheel overhead, which drives the holding and knotting devices, and a pit man from this gear and cam-wheel returns be neath the lower decking to a crank upon the binder-arm shaft and movesthe latter. I do not intend, however, to be limited to this particular form for the embodimentof my inven tion.

In the drawings,'Figure 1 is a side elevation in section of so much of the binding apparatus of said type containing my improvements as will serve to exhibit the chief operating parts; Fig. 2, a detail of the clutch and its dog and certain adjacent or connecting devices; Fig. 3, an alternative form of the double trip, and Fig. 4 a plan view of the apparatus with a portion of the decking broken away.

A A are bars or timbers upon which'the binding attachment is supported either in a fixed position orwith capacity for adjustmentalong the end of the harvester. B B are girts resting upon said bars and supporting the decking and certain of the operating-shafts. Mounted in suitable bearings in the framework is a shalt, D, continuously driven by means of a sprocketwheel, d, and chain-belt 01' other suitable instrumentality from the harvester-gearing, and in the present instance squared to permit the sprocket-wheel, held in position by a yo e an la o s p a ong it as the binder is adjusted. The shaft is usually cranked beneath the decking to drive two link-supported and alternately-moving packingarms, D, which rise through slots d in said decking and move downward along the throatway of the receptacle to feed the grain delivered from the harvester in wisps toward the compressing arm or stop, The bindingarm E, fast to a rock-shalt, F, is arranged to vibrate through a third slot, 6, in the decking and intermediate of the packer-slots, and a crank,f, upon the end of the binder-arm shaft is connected by a pitman,f, with the gear and cam wheel above mentioned and not herein shown. To aheel-extension, e, ofthe binderarm is pivoted the supporting-arm G, and a spur from said heel-extension is arranged to come against a lug on the supporting arm to form a look when the parts are in their position of rest, as in a patent heretofore granted 'to me on the 31st day of May, 1881, and numbered 242,177. The tripping-arm or compressorH is pivoted to the supporting'arm, as at h, and has in front of this pivot an eye, h, which receives the free'end of a trip-rod, h", atta hed to a rockshaft, I, raid rock-shaft having atits end an arm or crank, 13, arranged to bear against an adjustable seat upon a latch or dog, K, loosely sleeved to the binder-arm shaft, so as to raise said latch when the tripshaft'is rocked by thepivdtal 'motion of the compressor, the end of the latch, when it is down, stopping and serving to-disengage the clutch L upon the driving-shaft from the gearwheel L, normally running loose on said shaft, and when raised to permit said clutch to fly into engagement. A curved rod, M, attached to the crank of the binder-arm shaft, passes through a WQb OI flange upon the latch and receives a spring, m, which serves to return the latch into position to again open the clutch,

when the binder-arm falls at the conclusion of l the binding operation.

The parts as thus far described are of the common and well-known construction. Now, in carrying outiny invention I provide the decking h with a section, It, hinged at the head thereof, and, say, about six inches wide, lying centrally or in the line of the waist of thegavel,

extending nearly to the base of the compress or, and, if desirable, containing the slots for the packers and bindingarm. from the trip-shaft extends upwardly in an inclined direction toward the head of the receptacle, and to a point where the hinged section will rest upon it and be normally sustained somewhat above the surface of the surrounding decking. As thus constructed, pressure upon the yielding section will tend to rock the trip-shaft in the same direction as it would be carried by the yielding of the compressor, and will therefore start the binding mechanism.

Hereinabove the compressor has been described as pivoted to its supporting-arm, and connected by a trip-rod with the trip-shaft in the ordinary manner; but as the hinged section will be sufficient itself to determine the An arm, n,

IlO

tripping of the binder, this connection between the compressor and the rock-shaft may be dispensed with. If, however, it is wished to have both tripping agencies, then some compensating instruinentality must be introduced to allow for the differential motion of the compressorthat is, the play of the coinpressor will differ from the play of the hinged section, and if the arms proceeding from the rockshaft to each should be in close connection therewith and rigid with the shaft their action may not harmonize. This compensa tion may be obtained in several ways. For instance, in Figs. 1 and 4 the rod it, against which the hinged section bears, is rigid with the shaft, and the other rod, h, loosely sleeved thereon and provided with a shoulder or lug. h, which comes against a reverse shoulder or stop, it, upon the former. The hinged sec' tion, therefore, may of itself start the clutch in case the grain binds upon it without reach ing the compressor until sufficient is accuinit lated to form a gavel; or, if the grain travels freely forward and is packed against the coin pressor, then the latter, rocking, will bring the lug upon its trip-rod against the stop upon the other rod, moving the tripshaft alone or with the assistance of the hinged section.

in Fig. 3 both armsor rods are made rigid with the tripshat't and practically oractually integral with each other; but the eye in the compressor is'elongated, so that the rod ap pertaining thereto may have considerable play, and therefore not interfere with the perfect action of the hinged section of the decking when the latter starts first, while at the same time, since it normally rests against the bottom of the slot, being entirely sensitive to the yielding of the compressor.

This device I propose to make the subject of another application as a division of the present, and hence do not specifically claim it herein.

It is obvious that the principle of my in vention does not depend upon which side or wall of the picking-chamber the yielding decking is placed, nor upon the area or extent of such decking, nor upon the fact that said movable decking or table-trip plays between sections of adjacent decking, nor yet, so far as relates to the collateral tripping device, upon the particular form of said collateral trip, since there are many already well known which may be employed instead of the specific form of the latter described, whether in the same position or in some other where the pressure or resistance of the accumulating gavel will tend to act simultaneously upon both trips.

I claim as my invention- 1. In a grain-binder, a yielding table for receiving the grain, arrang d to rest upon an arm of the tripping mechanism, in combination with the tripping mechanism adapted to be thrown into engagement by the action of the accumulated grain upon the table.

2. The combination, with a trippingclutch to start the binder, and packing or feeding devices to compress the grain into the binding-receptacle, of adecking forming one wall of said receptacle, having a yielding section, and a connection between said section and the clutch to trip the latter by the yielding of the section.

3. The combination, with the grain-receptacle, of a yielding decking, and a connection between said decking and the trip-clutch, and a second or collateral tripping arm or surface against'which the gavel presses as it accumulates, also connected with the tripping-clutch to start the binder by the yielding of either said decking or said arm, or of both.

at. In combination with the grain-receptacle, packers feeding the grain therein, two yielding surfaces against which the gavel is piled by the packers in their action, and connections between said surfaces and the tripclutch to start the binder by their yielding.

5. In combination with the trippingclutch to start the binder, and with packing and feeding devices to deliver the grain into the hind ing-receptacle, a docking for said receptacle having a yielding section, a yielding arm or compressor closing the exit from said receptacle, and connections between said section and arm and the clutch, whereby the binder will be equally started by the yielding of one or the other, or of both.

6. In combination with the tripping-clutch to start the binder, and with the rock-shaft by which said clutch is dogged or shipped, a decking for the packing-chamber having a yielding section resting upon an arm from said rock-shaft, whereby the yielding of the deck ing as the grain is packed thereon will move the shaft and cause the engagement of the clutch.

7. In combination with the tripping-clutch to start the binder, and with the rock-shaft by which said clutch is dogged or shipped, a decking for the grainreceptacle, having a yielding section, an arm'from the rockshaft upon which said section rests, and a movable arm or outside compressor engaging with another arm from said rockshaft, whereby the shaft will be moved by the accumulation of grain against both the yielding section and the movable compressor.

8. The combination, substantially as described, of the hinged decking, the arm upon which it rests, the rock-shaft to which said arm is fixed, the latch operated by said rockshaft, and the clutch.

9. The combination, substantially as described, of the yielding decking, the arm upon which it rests, the rock-shaft to which said arm is fixed, the latch operated by said rockshaft, the clutch, and the outside compressor closing the exit from the grain-receptacle and adapted to be withdrawn from said passageway at the conclusion of the binding operation.

10. The combination, substantially as de scribed, of the tripping-clutch, two yielding surfaces in the grain-receptacle against which the accumulating gavel presses, connections between each of said surfaces and the clutch, and a compensating device in said connection, whereby either surface may be actuated at the proper time without interference by the other, or both operated concurrently.

11. The combination, substantially as described, of the tripping-clutch, its rock-shaft, the yielding decking and the compressing-arm, both connected to said rock-shaft, and a compensating device in such connection to avoid interference of the one with the timely action of the other.

12. The combination, substantially as described, of the hinged section, the arm upon which it rests, the rockshaft to which said arm is fixed, the latch operated by said rockshaft, the clutch dogged or shipped by said latch, the outside compressor closing the exit the movable supportingfrom the receptacle,

bar to which it is pivoted, and an arm extending from an eye in said compressor to the rock-shaft which moves the latch under such WILLIAM R. BAKER.
